Abstract: Recently, albino rainbow trout rarely occurs in fish farms in Turkey. In this study, it
was aimed to find the advantages and disadvantages of this species of trout over normal rainbow
trout and brook trout in terms of chemical composition and consumer acceptance. For this
purpose, protein, fat, moisture and dry matter contents of these species were determined.
Furthermore, consumer acceptance were surveyed by selling the fish in cleaned and packed
conditions using a questionnaire form placed under the packs. It was found out that brook trout
had the highest consumer acceptance, albino rainbow trout were in the second place and normal
pigmented trout had the lowest acceptance. Protein and fat contents of brook trout were also
slightly higher than the others. There were no significant differences in chemical contents
between albino and normal rainbow trout. Although, brook trout shows advantages over both
types of rainbow trout in terms of consumer acceptance and chemical contents, it reaches to its
marketable size much longer compare to others. Therefore, it is not economical to market this
trout with the same price. Albino rainbow trout reaches to the marketable size at the same time
with normal rainbow trout and quicker than brook trout. It also had better consumer acceptance
compared to normal one. In conclusion, the study showed that albino trout will sell better
compare to other types of trout.
